How do I interpret the SDR wind rose report?

Recommended Posts

The extension of each bar in the wind rose from ?innercircle? towards ?outer circle? represents the percentage of the time the windblew from those various directions.

The outer circle percentage indicatesthe amount of relative uniformity of the wind direction. For example, ifthere was a very strange site where the wind only blew from one direction allthe time, and never from any other direction, there would be a single bar goingout from 0 to 100%. Most sites, however, have more scatter with winddirections distributed among numerous directions.

All of the barsextending out will of course add up to 100% of the time period that wasmeasured. The ?outer circle? value is intended to provide some contextfor the graph so that at a quick glance, you can tell that at the site below,almost 30% of the time, the wind direction was southwest, another 25% or so wasnorth, and then the rest of the directions are distributed among the otherdirections to add up to the remaining 45%.
